Junior Full Stack Engineer

CtrLoop is focused on building AI-native enterprises, and they are seeking a Junior Full Stack Engineer. The role involves shipping features from the first week, working across backend and frontend technologies, and growing into a responsible engineering position while utilizing AI tools throughout the development process.

What you'll do:

• Ship your first flag-gated feature in your first weeks - small and well-scoped, senior-reviewed at the gates
• Build across all three surfaces: Python/Django backend, TypeScript web, React Native app (iOS + Android)
• Run the verification loop yourself: drive the flow, screenshot it, read the logs, gates green
• Contribute components and gotchas back to the Design System and conventions doc
• Own features end-to-end: design the frozen contract + simulator from the founder's PRD
• Build backend ∥ frontend in parallel with Claude Code, integrate, drive review
• Launch behind a flag with the success metric wired to a live dashboard before the flip
• Take on bigger features as you prove out
• Shadow, then co-run, then own external engagements on our portable pipeline
• Scope with the client, design the contract, build with Claude, demo, iterate live
• Launch on their stack, behind their flag

What they're looking for:

• Solid Python + JavaScript/TypeScript fundamentals and genuine AI-native fluency
• Python fundamentals you've shipped with - an API in Django/DRF/FastAPI, a real data model, tests; SQL basics
• JavaScript/TypeScript fundamentals - React on web; React Native is a plus you'll deepen here
• Evidence you ship - internships, side projects, hackathons, open source; working links beat résumé lines
• AI-native working style - an AI coding tool is already your daily driver, and you verify its output by running the app
• Written clarity - our pipeline runs on structured docs; if yours needs a follow-up conversation, it isn't done
• Ownership temperament - you batch questions with a recommended default attached, and proceed on the default when the answer is slow
• 0–2 years of experience - new grads welcome; show us shipped, working things
• Mobile exposure - React Native or Expo
• Postgres beyond the basics
• Feature flags, product analytics (Mixpanel) or error tracking (Sentry)
• LLM apps you've built, or prompt/eval tinkering

Benefits:

• Paid, timeboxed build exercise where using AI is required
